|
Kees Cook from the Ubuntu Security Team reported that the
|
|
CairoFont::create() function in the file CairoFontEngine.cc does not
|
|
verify the type of an embedded font object inside a PDF file before
|
|
dereferencing a function pointer from it.

<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user to open a specially crafted PDF
|
|
file with a Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview,
|
|
or Evince, potentially resulting in the execution of arbitrary code
|
|
with the privileges of the user running the application.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

All Poppler users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/poppler-0.6.3"</code>
